Theory of the nonreciprocal josephson effect

Webb20 jan. 2024 · We clarify the temperature scaling of the nonreciprocal depairing current near the critical temperature and point out its significant enhancement at low temperatures. It is also found that the nonreciprocal critical current shows sign reversals upon increasing the magnetic field.

WebbThe heterojunction between different materials often exhibits a rectifying effect; e.g., pn junction is used for diode. On the other hand, the Josephson junction between two different superconductors is assumed to show symmetric response between two directions of the current, i.e., the voltage drop V is antisymmetric with respect to the sign change of the … WebbWe here propose and develop a theory for an enhancement mechanism of the diode effect arising from spontaneous symmetry breaking. We show - both within a phenomenological and a microscopic theory - that there is a coupling of the supercurrent and the underlying symmetry-breaking order parameter. news in sbi https://bryanzerr.com

Webb2 juni 2024 · The resulting small amounts of nonreciprocity are too weak to be observed or matter. The aim of nonreciprocal acoustic wave engineering, then, is to strengthen these effects by developing techniques to enlarge nonreciprocity for small pressure amplitudes and slow-moving media.
